Display device, method for manufacturing the display device, and electronic apparatus including the display device

A method for manufacturing a display device, the method comprising:

• preparing a second substrate;
• forming a preliminary filler by providing a composition onto the second substrate;
• providing a display panel on the preliminary filler;
• inspecting the preliminary filler;
• and
• forming a filler by curing the preliminary filler,
• wherein the display panel comprises:
• a first substrate that is divided into an active area and a peripheral area adjacent to the active area;
• an insulating layer overlapping the active area and the peripheral area and disposed on the first substrate;
• a line overlapping the peripheral area and disposed on the first substrate;
• a pixel defining film in which a plurality of openings comprising a first sub-opening through a third sub-opening are defined and which is disposed on the insulating layer;
• a first electrode exposed through the first sub-opening, overlapping the active area, and disposed on the insulating layer;
• a second electrode extending from the active area to the peripheral area and disposed on the first electrode;
• an emission layer overlapping the active area and disposed between the first electrode and the second electrode;
• a metal layer exposed through the second sub-opening and the third sub-opening, overlapping the peripheral area, and disposed on the insulating layer;
• a first pattern part comprising a first portion of the line, a second portion of the metal layer, and a third portion of the second electrode and overlapping the peripheral area;
• and
• a second pattern part comprising a fourth portion of the line, a fifth portion of the metal layer, and a sixth portion of the second electrode and spaced apart from the active area, wherein the first pattern part is between the active area and each of the fourth portion of the line, the fifth portion of the metal layer, and the sixth portion of the second electrode,
• wherein the inspecting of the preliminary filler comprises comparing light transmittance of the first pattern part and light transmittance of the second pattern part with each other.

An electronic apparatus comprising:

• a display device, on which a sensing area is defined;
• and
• an electronic module disposed corresponding to the sensing area,
• wherein the display device comprises:
• a first substrate that is divided into an active area and a peripheral area adjacent to the active area;
• an insulating layer overlapping the active area and the peripheral area and disposed on the first substrate;
• a line overlapping the peripheral area and disposed on the first substrate;
• a pixel defining film in which a plurality of openings comprising a first sub-opening through a third sub-opening are defined and which is disposed on the insulating layer;
• a first electrode exposed through the first sub-opening, overlapping the active area, and disposed on the insulating layer;
• a second electrode extending from the active area to the peripheral area and disposed on the first electrode;
• an emission layer overlapping the active area and disposed between the first electrode and the second electrode;
• a metal layer exposed through the second sub-opening and the third sub-opening, overlapping the peripheral area, and disposed on the insulating layer;
• a first pattern part comprising a first portion of the line, a second portion of the metal layer, and a third portion of the second electrode and overlapping the peripheral area;
• and
• a second pattern part comprising a fourth portion of the line, a fifth portion of the metal layer, and a sixth portion of the second electrode and spaced apart from the active area, wherein the first pattern part is between the active area and each of the fourth portion of the line, the fifth portion of the metal layer, and the sixth portion of the second electrode.
